LOOSE-LEAF DEVICE.

Application filed May 31,

To all whom t may concern Be it known that l, dosiert-i linnn, a citizen ot the United Sta-tes, and a resident ot Chicago, in the county ot Cook and State of Illinois, have invented certain new and useful improvements in Loose-Leaf Devices7 of which the following is a specitication.

This invention relates to improvements in loose-leaf". binders, and more particularly to binding or locking devices for binders ot the character described.

The object of the invention is to provide a novel construction for the locking devices which coact with the binding posts to bind the leaves within the binder, these devices being ot hoolr form and adapted to he moved into and out oi' locking engagement with the binding posts by the addition oit operating fingers conveniently located.

A Jfurther object ot the invention is to provide simple and eiiective devices tor limiting the movement of the locking devices in order to afford a more dependable and positive locking action.

Further objects and advantages will be pointed out in the course ot the description which follows, and in connection with the accompanying drawings, in which- Figure 1 is a perspective view oit a binder .in open position. showing a preferred embodiment of tbc invention, and

Figure 2 is an enlarged detail view in section taken on line Qwf of Figure Il..

The binder comprises in general the usual stiff covers l and 2, hinged to a relatively iexible back section 3. A quantity of leaves or sheets 4; of a thickness not to exceed the space between covers is held within the binder by means of binding posts anchored in the lower cover 2 and extending through holes punched near the ma the leaves. it the tree ends et kare formed eyes iid- 5a adapt-ed to engage fastening members 6 6 mounted upon the front or top cover 1.

ln the preferred construction we binding posts and fastening members are employed, located near the lateral edges oit the binder. The 'formation of the fastening members will be understood from the following:

Secured to the inside surtace of the top cover and extending along the hinged edge thereof is a plate 7 serving as a support Jroi' the fastening members, as for other purposes hereinafter set forth, it desired, the

1922. Serial No. 564,964.

plate may be concealed from view beneath the inside layer et finishing material.

Each fastening member comprises a straight shank portion 6 terminating at its iii-ee end in a hooked end portion 6b extending at right angles to the shank portion. nt the opposite end ol? the shank, which entends substantially at right angles to the plate 7, is located a pin 8 whereby the tasten ing member is pivotally connected to the plate. integral with the shank portion and extending obliquely from the pivoted end thereof toward the near corner of the cover, is an operating finger 9 having a twisted tinger piece 9a at its end7 projecting a short distance beyond the adjacent edges of the leaves Ll.

integral with the plate 7, and extending along the inner edge thereof7 is a tubular flange 10 projecting` beyond the hinged edge ot the top cover l, and extending longitudinally throughout that portion ot the plate included between the l-astening members 6-6. Just inwardly 'from the extremities oit the iange l() are iormed notches l03-l0u located opposite the fastening members, and more essentially, in registering relation with the ends ot the posts 5-5, the ends oi the saine being slightly flattened so as to Ht snugly iu the nbtches with the eyes in registering relation with the passage Formed in the tubular ila-nge.

fis clearly shown in Figure l, the hooked end portions are adapted to extend into the open ends ci the tulfiular tlange through the eyes ot the posts registering therewith, and into the opening beyond, thereby providing a hinge-like connection permitting the necessary movement between the posts in the opening and closing ot the binder. The fasening members swung into and out of loclrlng engagement with the posts by press "ng in opposite directions upon the -r pieces 9a with thumb or ngers.

in order to limit the movement oit each tastening member, and acting first to hold. the posts in locking position; and second, to limit the withdrawal ci the hooked end portion 6a 'from the open end ont the tubular v.flange l0, the following device is employed.

From the metal of the plate 7 just beneath the fastening member is cut a spring clip ll, based inwardly beyond the fastening member, and extending substantially at right angles thereto toward the ends oit the ni'anipulation. Manifestly plate T. rThe clip passes beneath the shank portion 6 with its end spring nynvardly and overlapping the .Lager 9 of the fasteningn member. Formed in the surface of the iinn ger 9 is a detent l2 adapti-rzl tube engaged by the end of the clip. li/lorcovrr a stop lug 13 is formed on the clip between its end and the shank portion of the fastening wenn ber, the same being preferably struck up from the metal ot the clip, and in a position to be engaged by said shank portion.

The fastening members are preferably nnloclred by pressing the thumbs against the iingei.' pieces 9 in direction. to swing the shank portions outwardly and into the position shown by the lower fastening member in Fig. l. The movement of the shank portion is limited, however, by striking against the stop lug 13, thus preventing` the eye engaging portion 6b from being entirely withdrawn from the endl of the tubular flange, it being onlv necessary for the hooked end bto clear the notch in order to release the post. Hence the hooked end of the fastening` member is permanently supported within the tubular flange affordingl a guide and bearing therefor. Pressure in the opposite direction upon the finger pieces throws the hooked ends across the. notch l0 and into locking engr" ment with the oyes of the post (as shown by the upper firtening inemM bei in Figure it). In the lool ng position, the clip ll springs into the detent l2, thus` yieldingly retaining the posts against aceidental or undesired unlocking.

Ilhe forni of locking mechanism herein illustrated and described provides a particularly suitable arrangement for binders of the smaller size lwhich require not more than tivo binding posts, thus enabling them to be located near the ends, with the fastening members similarly located for convenient the structural features herein disclosed may be variously modied Without departing from the spirit of the invention, and therefore l do not Wish -to be limited except in so far as the inven- `pivotally mounted on, the other cover, and

providedvvith a hooked end portion adapted to engage the free end of said post, said isi/mera locking member comprising an operating nger, and yieldable means cooperating `vith said finger for retaining said locking inember in locking position. v
